Abstract
Embodiments described herein provided methods and apparatuses for determining Channel State Information Interference Measurement resources, CSI-IM resources, for interference measurement, wherein a New Radio, NR, base station is spectrum sharing with a Long Term Evolution, LTE, base station. A method in an NR base station includes determining a CSI-IM pattern for a CSI-IM resource, wherein the CSI-IM pattern is defined by one or more first OFDM symbols and a first frequency shift; and transmitting a Channel State Information Reference Signal, CSI-RS, according to a CSI-RS pattern, wherein the CSI-RS pattern is defined by a second OFDM symbol and a second frequency shift, wherein the first frequency shift and the second frequency shift do not overlap and wherein the one or more first OFDM symbols overlap with the second OFDM symbol.
